The microflow can have a parameter which should be the same as the object of your dataview. This way you pass that object to the microflow and commit the object. For going to the home page there is a specific action for that. See documentation here: https://docs.mendix.com/refguide/show-home-page
And you might want to take some learning paths in the academy section: https://academy.mendix.com/link/paths/40/Mendix-Basics
